A new analytical technique that uses infrared spectroscopy to study light-sensitive organic materials could lead to the development of cheaper, more efficient solar cells. Using infrared (IR) spectroscopy to study the vibrations of atoms within the material, the technique provides information about the movement of electrons within a film of carbon-based materials.
